4D Breast, Oncology, Palliative Care Flashcards
(40 cards)
Breast conditions
- Duct ectasia. Symptoms? (2) Common age of presentation?
- Duct ectasia: non-malignant breast disease with thick green nipple discharge, commonly with a peri-areolar lump, occurring with breast involution (menopausal change).
Duct ectasia reflects a shortening and widening of the terminal breast ducts around the nipple.
Breast cancer - hormonal therapy
- Tamoxifen
- Class of drug?
- Indication?
- Side effects? - Anastrozole.
- Class of drug?
- Indication?
- Side effects?
- Selective oestrogen receptor modulator (SERM), which blocks oestrogen from acting at its receptors.
Adjuvant hormonal therapy is offered if tumours are positive for hormone receptors. Tamoxifen for 5 years after diagnosis in PRE- and PERI-menopausal women.
Side effects: increased risk of endometrial cancer, VTE and menopausal symptoms.
- Aromatase inhibitor. Reduces the oestrogen levels in the body and is typically given for 5 years.
Used in the management of hormone-receptor-positive (ER +ve) breast cancer patients in POST-menopausal women.
Anastrozole = After menopause
Side effects: Hot flushes, insomnia and low mood.

Symptoms?
Treatments? - Neutropenic sepsis
Symptoms?
Treatment?
- Superior vena cava (SVC) obstruction is an oncological emergency caused by compression of the SVC. It is most commonly associated with lung cancer.
Symptoms: Dyspnoea, swelling of face, neck and arms , conjunctival and periorbital oedema,
headache: often worse in the mornings
visual disturbance
pulseless jugular venous distension
NB. peripheral oedema WITHOUT pulmonary oedema.
Treatments: Endovascular stenting, radical chemotherapy, chemo-radiotherapy.
- LOW temp.
Blood cultures and IV abx within 1 HOUR
Cytotoxic agents
‘Toxicity bear’
What drug is associated with the following:
- Cardiomyopathy
- Haemorrhagic cystitis
- Peripheral neuropathy
- Neutropenia
- Pulmonary fibrosis
- Ototoxicity, nephrotoxicity, hypomagnesaemia.
- Myelosuppression, liver fibrosis and oral mucositis
- Doxorubicin (lymphoma)
- Cyclophosphamide (lymphoma, leukaemia)
- Vincristine (lymphoma)
- Docetaxel (breast and lung cancers)
- Bleomycin (lymphoma)
- Cisplatin
- Methotrexate
Human Papillomavirus (HPV).
- What strains cause cervical cancer?
- What strains cause genital warts?
- What strains cause common warts?
- 16, 18 & 33
- 6 & 11 (and thereby low risk for cervical cancer)
- 2, 7 & 22 cause common warts.
Metastases
- Which 5 cancers most commonly metastasise to BONE?
- Where does BREAST cancer typically metastasise to?
- BLT with ketchup and pickles
Breast (both lytic and sclerotic lesions)
Lung (lytic)
Thyroid
Kidney
Prostate (sclerotic)
Osteoblastic lesions (sclerotic)
Osteolytic lesions
- Breast metastasis: 2L’s 2B’s
Lungs
Liver
Bones
Brain
Drug treatments
- Spinal cord compression (neoplastic)
- Oral dexamethasone 8mg BD
(or 16mg IV stat?)
What are the differences between
Multiple endocrine neoplasia type I
and
Multiple endocrine neoplasia type II?
MEN type IIb - autosomal dominant.
Sx - phaeochromocytomas, medullary carcinoma of the thyroid
DRUGS for end of life care
- Class of drug
- Therapeutic effects
- Glycopyrronium bromide
- Midazolam
- Benzydamine hydrochloride (mouthwash or spray)
- Anticholinergic (antimuscarinic) agent → inhibits the action of acetylcholine (does not cross BBB so does not cause confusion)
- Reduces production of saliva → reduces respiratory secretions
- Alleviates bowel colic
hyoscine hydrobromide, hyoscine butylbromide have similar actions.
- Midazolam - benzodiazepine. Manage terminal agitation and restlessness.
- Sedation
- Muscle relaxation - Mouthwash or spray - painful mouth . AKA Difflam. Numbs throat in paediatric tonsillitis also.
Performance status informs cancer treatment
Describe categories 0-5?
0-1 : offer cancer treatment
2 : Individual basis
3-5 more side effects from treatment - risks outweigh benefits. Not suitable for cancer treatment.
Side effects of chemotherapy
Important - neutropenic sepsis
https://www.healthline.com/health/cancer/effects-on-body#circulatory-and-immune
Immunotherapy
- Imatinib
- Herceptin
- CML. Acts on BCR-ABL translocation (Philadelphia chromosome)
- HER2+ve breast cancer
OSCE Tips
PHYSICAL EXAMINATION
Look for radiotherapy tattoos
Explain cancer treatments
1. Radioisotope therapy
- Thyroid, iodine
Lung Cancer
Red flags?
small cell 13%
- very aggressive even if small
lesion
Red flag - pain at night
Tracheal deviation caused by one of 3 things - mass, fluid or air (pneumothorax).
Investigations
Confused patient - what to exclude?
Confused patient
- Exclude UTI, chest infection, sepsis (Urine dipstick / MSU / CXR)
- Hypercalcaemia (Bloods)
- Dehydration (U&Es)
- Brain mets, stroke (Head CT)
Hypercalcaemia treatment
- IV fluids
- IV pamidronate 60-90mg over 2 hours.
Prostate cancer most common type?
Describe Gleason score 1 -5
95% adenocarcinoma
5% other eg carcinoma
Investigation
- PSA x2
- DRE
- Pre-biopsy MRI
- Transperineal Biopsy
Staging - CT scan if PSA >40, bone scan, PET CT if ?mets.
Gleason scoring 1-5, 5 is worst (undifferentiated, more aggressive).
eg 3+4 means 3 most common, 4 second most common.
Describe TNM staging 1-4 in prostate
Treatment - for each stage?
Early (T1-2, N0, M0)
Observation
‘Watchful waiting’
‘Active surveillance’
Radical treatment
Surgery
Prostatectomy
Pelvic lymph node dissection
Radiotherapy
External beam radiotherapy
Interstitial brachytherapy
+/- Neoadjuvant or adjuvant hormone therapy
T1 or T2 weighted MRI?
T2
This image - T1?
Level of neutropenia?
Platelet count to need platelet transfusion?
Neutrophils <1
Neutropenic sepsis - eg Tazocin or Meropenem, +- Gent +- Vanc
Platelets - 10
If infection - 20
Surgery - 50?
What is frailty?
How is it measured?
Ability to bounce back. Takes longer to recover, and does not recover back to previous level of function.
Can be described as an age-related condition characterised by a decline in physiological capacity across several organ systems, which results in a higher vulnerability to stressors and unfavourable outcomes
Rockwood frailty score.
Random facts
- Vivid dreams
- Falls
- Visual hallucinations
- What blood abnormalities cause confusion
- Normal pressure hydrocephalus symptoms?
- Can mean cardiac ischaemia / atypical MI no chest pain
